2 is correct.

X marks the spot for the next quiz. Only 12 questions this time because it's tough to come up with TV related stuff for this letter. Always first name first unless the question specifically asks for a surname.

1. The series, while not primarily parallel Earths focussed, looked at at least four such Earths during its run.
2. Bryan Cranston guest starred as a villain on which series that fits this theme?
3. This character was engaged to a demoness but left her at the altar.
4. This is a singing tryout series
5. Which character from which show later migrated to the comics?
6. On one sci-fi series this character played by this actress replaced a similarly but not identically named character (character and actress fit this theme, show name does not).
7. What was TV entertainer Cugat's first name?
8. This titular hero sometimes teamed up with a demigod.
9. Who played Gregory on The Walking Dead?
10. On Spider-Man Unlimited, Spider-Man met this hero on Counter Earth.
11. This spacefaring hero has appeared in the DC Animated Universe.
12. This is the presumed surname of one of the Allies for Peace in their non-super identity.
 

Those are correct. For question 1, I've never gotten into X-Files so I don't know if they did that multiple times. The wording for that question was entirely the result of my starting on the Marvel collages. Once you start listing off all the characters, the amount of use of alternate realities becomes very apparent. There's even at least one reality that has nothing to do with people trying to change history.

7 is correct. That leaves:

9. Who played Gregory on The Walking Dead?
11. This spacefaring hero has appeared in the DC Animated Universe.
12. This is the presumed surname of one of the Allies for Peace in their non-super identity.

Remaining answers:
9. Who played Gregory on The Walking Dead?
Xander Berkeley

11. This spacefaring hero has appeared in the DC Animated Universe.
Xax of Xaos, member of the Green Lantern Corps (e.g. Superman: The Animated Series)

12. This is the presumed surname of one of the Allies for Peace in their non-super identity.
Xavier (The Allies for Peace were the 1966 Marvel Super Heroes cartoon versions of the X-Men. Individual members had the same names as their X-Men counterparts),

The next quiz is on the letter Y. As always first name first unless the question asks for the surname. Actor is gender neutral.

1. Groucho Marx hosted this game show.
2. Paul Reubens starred in this computer game based series
